The boxed kits, compared
Only what the listings publish. Note how many of them do not state a steel gauge — in this category that is the figure that separates a fireplace that lasts a decade from one that warps in three seasons, and almost nobody publishes it.

| Gardenbee 63 in | Propane | 63 in wide | Not applicable | Built-in tank | CSA certified |
The two gas kits are the only units here that state a certification, which is worth weighing. A CSA-certified propane fireplace has been tested as a gas appliance; a steel wood-burning fireplace is a fabricated object with no equivalent standard behind it. That does not make the wood ones bad, but it does mean the published facts are thinner.
Chimney height is the spec that actually matters
A fireplace earns its keep over a fire pit by taking smoke upward and out of your face, and that only works if the flue is tall enough to establish a draw. The EROMMY’s published 57 inches is meaningfully different from the Aoxun’s 36, and in practice the difference shows up on a still evening, when a short chimney lets smoke roll out of the opening instead of up the flue.
Two related points people get wrong. A decorative chimney stack is not a flue — what matters is a clear, continuous path from the firebox out of the top, not the silhouette. And no boxed fireplace’s chimney makes it safe to run under a solid roof: we deal with that properly on outdoor fireplaces for covered patios, and the short version is that a patio ceiling is combustible material above a flame and these appliances are specified for open-air use.
Assembling one, realistically
- Budget an afternoon and a second pair of hands. These arrive as steel panels, a firebox, a chimney section or two and a bag of bolts. The chimney assembly in particular is awkward alone.
- Build it where it will live. Assembled, a steel fireplace is heavy and tall, and walking one across a lawn is how panels get bent. Decide the spot first, including its clearance from the house wall, the fence and anything overhanging.
- Level matters more than you expect. A fireplace is tall and narrow, so a slight slope becomes a lean, and a lean becomes a tipping risk when someone leans on it. Pack the feet properly on a lawn.
- Check every bolt after the first two or three fires. Steel expands and contracts dramatically through a burn cycle, and fasteners settle. Ten minutes with a wrench after the first weekend is the best maintenance you can do.
- Plan for a cover from day one.Thin steel, outdoors, uncovered, is rust. A cover costs a fraction of the fireplace and roughly doubles its usable life — our covers page explains what a waterproof rating actually means.
When masonry is the real answer
A modular masonry kit is the right purchase in a specific situation: the fireplace is part of a hardscape you are building anyway, it is never moving, and you want it to read as architecture rather than as a product. It needs a poured and cured footing, a mason or a genuinely competent DIY build, and in many jurisdictions a permit. The components arrive as pre-cut block or interlocking units with a firebox and flue sized to go with them.
That channel is hearth and landscape dealers, and it is why those kits are not ranked on this page: no live retail listing means no verifiable spec or price, and we will not invent either. What to ask a dealer for, with your site dimensions in hand: firebox opening size, total assembled footprint, flue height above the firebox, the footing specification, and whether the quote includes delivery to the back of the property — a pallet of block left at the curb is a real problem.
A middle route exists and is worth knowing about. A drop-in fire pit kit — a steel pan or burner you build a block surround around — gets you the built-in look for a fraction of a masonry fireplace’s cost, because you are only buying the metal part and the surround is ordinary blockwork. You lose the chimney, which means you are back to a circle of smoke rather than a directional fire, and fire pit vs outdoor fireplace is the page that decides whether that trade suits you.
Wood or gas, in this category specifically
Woodgives you the fire people actually want, costs less to buy, and in a tall-chimney design genuinely vents the smoke. It needs dry fuel — the EPA’s guidance is below 20 percent moisture, seasoned six months, stored off the ground with only the top covered — and it needs ash cleared and a screen for embers. Both Panovue and Aoxun include integrated wood storage, which on a small patio is more useful than it sounds.
Gasgives you a certified appliance, instant off, no ash and no embers, which is why it is often the only legal option under local fire restrictions. Both Gardenbee units publish 50,000 BTU and CSA certification, and both have somewhere designed for the cylinder. The 63-inch is a piece of outdoor furniture rather than an appliance — it anchors a wall-side seating area in a way nothing else here does. Our outdoor gas fireplaces page ranks that field, and wood-burning outdoor fireplaces does the same for cordwood.
